Next are some summary statistics.

First, here’s the breakdown of parcels by residential zoning type in General Plan 2035. The parcel shapes and zoning were pulled from ArcGISOnline. Note there were some inconsistencies in APN designation between this zoning file and the County’s Assessor record. 6 residential parcels were manually re-coded from Assessor APN to EPA General Plan APN.

New state regs require ADUs to be allowed in all residentially zoned parcels.

Of residentially zoned parcels, below is the breakdown of property use code according to the County Assessor, which should represent as of early 2019 the existing use. The table also notes which PUCs we considered to be “ADU eligible” for our analysis, and completed the buildable area analysis for. Note the following key caveats:

\(~\)

# hist(epa_parcels_adus$max_detached_buildable_area, breaks=c(seq(0,1200,50)),xlim = c(0,1200))

\(~\)

# hist(epa_parcels_adus$max_attached_buildable_area, breaks=c(seq(0,1200,50)),xlim = c(0,1200))
